On the other hand, FIGS. 5 and 6 illustrate a touch pad unit 400 according to another embodiment of the present invention having a different configuration and placement order from the touch pad unit 400 of the touch switch attachable to a wall illustrated in FIGS. 3 and 4.

The touch pad unit 400 of FIG. 3 has a structure in which the main PCB 410, the LCD panel 420, the rubber packing 440, and the bezel 430 are sequentially coupled on the fixing plate unit 300, whereas the touch pad unit 400 of FIG. 5 according to another embodiment of the present invention of FIG. 5 has a structure in which a bezel 430, a main PCB 410, and an LCD panel 420 are sequentially coupled on the fixing plate unit 300.

That is, as illustrated in FIGS. 5 and 6, the touch switch attachable to a wall includes: a switch box unit 100 inserted into an embedded box formed in a wall; a back cover unit 200 inserted into the switch box unit 100, with a plurality of PCBs 330 stacked on each other being disposed in the back cover unit 200; a fixing plate unit 300 coupled to the switch box unit 100 to support an external surface of the back cover unit 300 penetrating the fixing plate unit 300; and the LCD touch pad unit 400 coupled to one end of the back cover unit 200 penetrating the fixing plate unit 300, electrically connected to the plurality of PCBs 330, and inputting switching driving information to the plurality of PCBs 330 in a capacitive touch method.

In addition, the bezel 430 has the other end in which a groove accommodating the main PCB 410 and the LCD panel 420 is formed, and includes a plurality of main PCB separation pins 432 to maintain a predetermined distance from the main PCB 410.

The main PCB 410 is electrically connected to the plurality of PCBs 330, and an area of the main PCB 410 is wider than that of one end of the back cover unit 200. A memory insertion portion 411 may be formed in one surface of the main PCB 410, removable memory (SD, not shown) being inserted into the memory insertion portion 411 and being electrically connected to the plurality of PCBs 330. The removable memory can pre-store or change and store configuration information of content, a tag, a node, or the like required for a switch operation. The configuration information stored in the removable memory can be transferred to the main PCB 410. In addition, since the removable memory is attachable to or detachable from the memory insertion unit 411, the ease of operations may be obtained when an operator maintains or upgrades firmware.

The LCD panel 420 has a function for transferring an input signal to the main PCB in a capacitive touch method.

The LCD panel 420 may display various configuration screens, and a user may input a corresponding switching command with a finger through the configuration screens and transfer the corresponding switching command to the main PCB and the plurality of PCBs so that a switching operation is performed.

Components illustrated in FIG. 5, i.e. the switch box unit 100, the back cover unit 200, the plurality of PCBs 330, and the fixing plate unit 300, have the same structure and placement order as those illustrated in FIG. 3. The back cover unit 200 according to another embodiment of the present invention extends through the through-hole 310 of the fixing plate unit 300 and stably supports the back cover unit 200 by closely contacting a side surface of the back cover unit 200 through the support part 320 extending from the inner peripheral surface of the through-hole 310.

As illustrated in FIG. 6, one end of the back cover unit 200 has a structure coupled to protrude outward from the bezel 430 and the other end thereof is disposed in an inner space of the switch box unit 100. The back cover unit 200 and the bezel 430 have a plurality of back cover bolt holes 210 and a plurality of bezel holes 431. The back cover unit 200 and the bezel 430 are configured to be brought to each other according to the corresponding shapes thereof and then to be coupled to each other using bolts.

The LCD touch pad unit 400 is electrically connected to the plurality of PCBs 330, and switching driving information is input to the plurality of PCBs 330 in a capacitive touch method.

The LCD touch pad unit 400 includes the main PCB 410, the LCD panel 420, and the bezel 430, which are coupled through a coupling means such as a double-sided adhesive tape, an adhesive, a nut, or the like.

In addition, a sealing rubber packing may also be installed on the bezel 430 and an edge of the LCD panel 420 as illustrated in FIG. 3 to maintain a seal.

On the other hand, referring to FIGS. 8 to 10, the touch switch attachable to a wall according to the present invention may be a switch using a capacitive touch pad thin fill transistor (TFT) LCD, the switch being able to selectively use one of the Zigbee communication system and the E/F2 or use a combination of the Zigbee communication system and the E/F2 combined through a gateway.

This allows lighting to be wirelessly controlled through a Zigbee device provided in the touch switch attachable to a wall, and also allows communication with a main controller and a control device and power to be supplied thereto through access to the E/F2.

In response to the E/F2 and the Zigbee communication system, wired and wireless devices can be controlled through an address terminal unit.

Therefore, various lighting control scenes can be set using an E/F2 network, and group setting can be performed using a DALI network.

In particular, the touch switch attachable to a wall according to the present invention can independently select or combine the Zigbee communication system and the E/F2 to perform on/off control or dimming control of lighting devices according to the service environment.

In addition, a button attribute, a screen configuration, and an operation function can be edited in a PC through a touch LCD switch editor and a simulator of the touch switch attachable to a wall, and the button attribute, the screen configuration, and the operation function can be stored a removable memory card (SD card) and be stored in a touch LCD switch (TLS). This is to provide a user-friendly editing function.

A user may apply a scenario based on timed-based lighting color-temperature setting (morning/evening warm white and daytime cool white) to a lighting device and operate the lighting device by easily constituting group control/individual control of the lighting device on a switch screen through such a function. The user may perform such an operation using a button to display the operation on a touch LCD switch (TLS) screen.

A switch controlling a lighting device may be used in plural due to necessity of a user and a limitation of a circuit configuration in an inner space. In this case, in order to solve a problem that the user has a difficulty in finding a switch interworking with the lighting device, the touch switch attachable to a wall according to the present invention may distinguish a lighting device by displaying a plan view of a building on a touch LCD switch (TLS) screen and may explicitly perform individual control.

In addition, according to the present invention, there may be a problem that power consumption is rapidly increased when power is supplied to a driving device and a backlight unit of an LCD through an E/F2, but a trickle charge function may be used through a power storage device (battery), a charging circuit, and a keying circuit. Charging is performed by performing a trickle function during a slim mode by adding a battery cell, and energy stored in the battery is used during an LCD touch operation and a monitoring function, thereby further saving energy.

High supply current and energy are required when a user performs an LCD screen touch. However, since a substantial operation time of the user is short, instantly generated supply current and energy are only required. Accordingly, when the user performs the LCD screen touch by performing a trickle charge function, system power is not used and current stored in the battery is used, i.e. an auxiliary battery is used, thereby maintaining a stable system power state. At the same time, when a sleep function is performed, charging is performed with a diminutive current by performing the trickle charge, thereby saving energy.

Since a general touch switch operation complexly involves many functions, supply current is high. However, since a finger touch according to the present invention performs a simple function, a very small amount of current is used during the operation, thereby saving energy. Although not shown in the drawings, three finger touch buttons in addition to the an LCD touch are disposed in the LCD touch pad unit 400, and thus, in a situation in which a user operation is required when a sleep function is performed, a wakeup function is performed through a finger touch to perform the wakeup function with low supply current and an easy operation, and a picture, content, a tag setting screen movement of several scenes set by the user may be easily used as in a smartphone.

In addition, the LCD touch pad unit 400 includes a backlight unit providing LCD light, and the backlight unit may variably adjust a lighting level in a set range on a command window visualized in an LCD through a capacitive touch and may enable the LCD window at the time of a touch response.

According to embodiments of the present invention, through the configuration and the operation described above, contents of a screen required for a switching control operation may be composed on an LCD using a switching driving program, and a tag about a picture file and a tag about a node may be registered through removable memory.

In addition, according to embodiments of the present invention, information on content, a tag, or a node may be produced in a PC to store the information in removable memory, thereby simply registering the information.

In addition, according to embodiments of the present invention, several screen configurations may be composed on an LCD, thereby controlling one of the several screen configurations and performing a complex function.

Furthermore, according to embodiments of the present invention, a capacitive touch pad may be used to enable an operation when a user touch is sensed, thereby efficiently saving energy.

While the touch switch attachable to a wall according to the present invention has been described with reference to some embodiments, it will be apparent to those skilled in the art that various modifications can be made without departing from the spirit and scope of the invention.
